FIG. 1 illustrates a schematic view of anexemplary video system 100. Theexemplary video system 100 generally includes at least one video subsystem, such asvideo subsystems video system 100 also includes at least one video processing system, such asvideo processing system 130 and at least oneexternal device 140. - The
video subsystems external device 140 via thevideo processing system 130 during theshift 130. Once the shift has ended, thevideo subsystems external device 140 directly. Theexternal device 140 may include a storage system, an input/output interface, and/or other external devices as desired. - The
video processing system 130 is configured to communicate with thevideo subsystems external device 140, as will be described at appropriate points hereinafter. Such a configuration can allow for a more complete transfer of video data that occurs during a shift. - Further, the
video processing system 130 may allow an administrator to preview the video data during a shift. Previewing the video data during a shift may allow the administrators to identify video data that should be acted on as soon as possible, thereby allowing earlier access to potentially relevant video data. The general configuration of theexemplary video subsystems video processing system 130 will first be discussed, followed by a more detailed description of various components with thevideo subsystems video processing system 130. - As illustrated in
FIG. 1 , thevideo subsystem 110 generally includes avideo source 112 and aprocessing subsystem 114 associated with aplatform 116. In the illustrated example, thevideo source 112 is in communication with theprocessing subsystem 114, which in turn is in communication with thevideo processing system 130. - Similarly, the
second video subsystem 120 may include avideo source 122 and aprocessing subsystem 124 associated with aplatform 126. Thevideo source 122 is in communication withvideo processing subsystem 126, which in turn is in communication with thevideo processing system 130. - In at least one example, the
processing subsystems video processing system 130. In other examples, theprocessing subsystems video processing system 130. - The connections and links between the elements of
video system 100 may use various communication media, such as air, metal, optical fiber, or some other signal propagation path—including combinations thereof. Such connections may be direct links, or they might include various intermediate components, systems, and networks. - The
video processing system 130 includes at least one device configured to receive transmissions ofvideo subsystems video processing system 130 includes at least one server configured to communication with either or both of thevideo subsystems servers FIG. 1 illustrates thevideo subsystems video processing system 130 to emphasize thevideo subsystems servers video processing system 130. Thevideo processing system 130 then processes the video data to a desired extent. - Once the
video processing system 130 has processed the video data, thevideo processing system 130 transmits some or all of the video data to anexternal device 140 or other external device. By providing a plurality of pathways which the video subsystems 110, 120 may use to transfer video data from their locations to thecentral storage systems 140 during their shifts, thevideo processing system 130 may increase the amount of video data from each shift thevideo system 100 is able to retain. - Further, such a configuration may allow the
video processing system 130 to provide a preview of video data. Such a situation may be desirable when relevance of selected video data is unclear and thus it is unclear whether it would be desirable to analyze the selected video data immediately or whether it may be suitable to analyze the selected video data at a later time. To this point, the locations of thevideo subsystems servers - One exemplary arrangement is illustrated in more detail in
FIG. 2 . As illustrated inFIG. 2 , avideo system 200 may include a plurality ofvideo subsystems video subsystems FIG. 1 or as will be described with reference toFIG. 4 . In any case, thevideo subsystems transmission system 230 at various locations within the region. - In the illustrated example, the processing/
transmission system 230 includes a plurality ofhotspots hotspots hotspots - The
hotspots hotspots video subsystems video processing system 230 when thevideo subsystems hotspots video subsystems - In the illustrated example, the
video subsystem 210 is shown in range of thehotspot 231. While thevideo subsystem 210 is thus in range of thehotspot 231, thevideo subsystem 231 automatically transmits video data to thehotspot 231, which in turn transmits the video data to anexternal system 240. - The selection of which video data the
video subsystem 210 transmits may be determined in response to user input, by system intelligence, or by some combination thereof. The transmission of video data to thehotspot 231 may part of a download operation and/or may be a preview of video data that has been identified for potential investigation. Each of these two scenarios will now be discussed in more detail. -
FIG. 3 illustrates amethod 300 for transmitting video data from a video subsystem to according to one example. As illustrated inFIG. 3 , themethod 300 begins atstep 310 when a video system begins by storing video data on a video subsystem that includes a mobile platform. The video data may include any number of scenes. - As previously discussed, the mobile platform may include one or more video subsystem that travels along various routes within a geographical region. The video subsystems may be configured to communicate with one or more hotspots within the geographical region. Accordingly, the method includes searching for hotspots at
step 315 as the video subsystems travel along the various routes. Searching forhotspots 315 may include searching for wireless hotspots. - In at least one example, the
method 300 may also optionally include atstep 320 receiving selection input to identify one or more scene for investigation by an administrator. This step is shown in parallel with the steps of storingvideo data 310 and searching forhotspots 315 since all three of these steps may be performed on an ongoing basis. - As shown in
FIG. 3 , if a hot spot is not available (NO, step 330), the video subsystem continues to search for a hotspot until an available hotspot is in range. Once a hotspot is available (YES, step 330), the method includes connecting to a system via the hotspot. Connecting to a system via the hotspot may include connecting to a processing/transmission system that is in further communication with an external device, such as a storage system or an I/O interface. - How the video subsystem transmits video data may depend on whether a scene has been selected at
step 340. If no scene is selected (NO, step 340), then the video subsystem transmits the next scene in a transmission queue atstep 345 to an external storage device, such as a storage system. Such an example may occur where no previews are available in the optional steps described above or if no input selection has been received to select a scene. A transmission queue may be merely the earliest video data yet to be transmitted or may be any other arrangement of video data, such as video data that have been selected for retention, but which have been identified as being suitable for analysis at the end of the shift. - However, if a scene has been selected, various steps may be performed to indicate how the video data should be treated. Referring still to
FIG. 3 , once selection input is received atstep 320, the method includes generating a preview of the scene identified by the selection input atstep 347. Previews may be generated in any desired format, such as a video clip, video stills, or any other desired format. - If a scene has been selected the method includes transmitting the preview at
step 350. For example, the preview may be transmitted to an external I/O device. In at least one example, transmitting the preview may include transmitting the scene to an I/O device for an administrator to view. In at least one example, the preview may be transmitted once the preview is generated. Further, the preview may be generated using any suitable network including the processing systems described herein, wide area networks, cellular networks, other networks, or combinations thereof. - As a result, the method includes determining whether to download the identified scene at
step 355. As previously introduced, the preview may be generated and sent to an administrator atsteps 325 and 350. For example, an administrator may provide instructions to the video subsystem to download the scene or not atstep 355. These instructions may be provided from the same network used to transmit the preview or may be provided in some other manner. If the instructions indicate the scene is to be downloaded, the video subsystem prioritizes delivery of that scene. As a result, when the video subsystem has coupled to a system via a hotspot as described in steps 310-340, atstep 340 the system then determines that a scene has been selected (Yes, step 340) and the video subsystem transmits the selected scene to an external device atstep 345, such as a storage system accessible by an administrator. - If, however, the instructions indicate that the scene should not be downloaded immediately (NO, step 355), the video subsystem continues to store the video data and handles the video data normally, as indicated by the arrow from the NO decision returning to the first step of the process. In such a process, the video data may be transmitted when in turn as part of the transmission processes described herein.
- Though two video subsystems are shown, it will be appreciated that the
video system 200 may include any number of video subsystems. Further, while twohotspots - As introduced, any number of video subsystems may communicate with the
external device 240 via thehotspots video processing system 230. Communication between several video subsystems and thevideo processing system 230 may result in bandwidth concerns asvideo processing system 230 may not have an input port capable of receiving full resolution, real time video from all of the video sources. - In such a case, it may be desirable to incorporate some video processing functionality within each of the video sources and video transmission systems associated with each of the carriers such that the bandwidth requirements between the various video sources and
video processing system 130 are reduced. An example of such a video source is illustrated inFIG. 4 . -

Thevideo source 400 includes alens 402, asensor 404, aprocessor 406,memory 408, and acommunication interface 410. Thelens 402 is configured to focus an image of a scene on thesensor 404. Thelens 402 may be any type of lens, pinhole, zone plate, or the like able to direct light to and/or focus an image on thesensor 404.
